The article reviews two books: "The Physiology of the Salivary Glands" by A. S. V. Burgen and N. G. Emmelin, and "Experimental Immunochemistry" by Elvin A. Kabat and Manfred M. Mayer. The first book is a comprehensive monograph covering the physiology, anatomy, and pharmacology of the salivary glands. It is well-organized, with extensive references and a clear structure. The authors, from different medical traditions, present a truly international body of research. The book is particularly stimulating in its discussion of theories on salivary secretion, challenging the traditional view that acini are the sole secretory units. The second book is a detailed guide to immunological and biochemical techniques, with a focus on chemical immunology. It includes a large amount of new work and is now up to date, though it is somewhat expensive. The book is essential for immunological and biochemical research, though it does not cover all aspects of immunology, such as cytology and immunopathology. The article also reviews other books, including "Preparation and Characterization of Ferritin for Electron Microscopic Studies," which is a valuable bench book for immunological research. "Relief of Symptoms" is a practical guide to symptom management but is lacking in some aspects. "Uveitis and Toxoplasmosis" is a concise but essential read for ophthalmologists and general physicians. "Psychosomatic Aspects of Pediatrics" is a valuable resource for pediatricians interested in the psychological aspects of children's health.The article reviews two books: "The Physiology of the Salivary Glands" by A.
